Applying Quantum Entanglement to Search for New Physics at TeV Energies

Collisions of electrons and positrons can create B-meson particles in an entangled state. I will explain how the BABAR experiment has applied the associated Einstein–Podolsky– Rosen effect to study differences between matter and antimatter known as CP violation, as well as how it has used the effect to observe the “quantum arrow of time”. The Belle II/SuperKEKB facility that is currently being commissioned in Japan will extend these studies and will be sensitive to new physics at energies well above those available at the Large Hadron Collider. I will describe how it will do so and investigate the evidence for new physics published by BABAR and recently corroborated by the Belle and LHCb experiments.

Short bio: Professor Roney studies fundamental particles and interactions and the development of subatomic particle detectors. He has published widely on electroweak physics, the flavour sector of the Standard Model, and on various related detector technologies. His recent work involves searches for evidence of unexplained new fundamental physics in the flavour sector of the Standard Model using precision measurements as well as through direct searches for new particles and processes. He has led international teams in both the OPAL Collaboration at CERN and BABAR Collaboration based at the SLAC National Accelerator Laboratory in California. Dr. Roney currently leads the BABAR Collaboration as its Spokesperson and is working on the world’s next generation 10.58GeV electron-positron collider project: a Japanese facility designed to search for new physics at the precision frontier with 40 times the intensity of existing facilities. Professor Roney has served as President of the Canadian Association of Physicists and is the Director of the Institute of Particle Physics (Canada).
